The Photizo I used on my English Bull Terrier did wonders for his skin rash. He has a bad medical condition where his skin on his belly and under his legs would flare up and itch uncontrollably. After using the Photoizo I saw an immediate difference. After just a few days the rash had completely cleared up and hasn’t returned. It was the only thing that really helped, and I can tell you I tried everything. Thank you very much for an awesome product!
